Thomas Barnardo tells the story of his life. We see Barnardo teaching at the Ragged School and discovering homeless boys sleeping on London's rooftops. And we see him setting up the first home for London's street children.

Rosa Parks tells the story of her life. She shows how her refusal to give up her seat on the bus in Alabama in 1955 changed the rules and led towards equality and justice for everyone, whatever the colour of their skin.
